Genome-wide identification of the NAC family in Hemerocallis citrina and functional analysis of HcNAC35 in response to abiotic stress in watermelon

Introduction NAC (NAM, ATAF, and CUC) transcription factor family, one of the important switches networks in plants, functions plant growth, development, stress resistance. Night lily ( Hemerocallis citrina ) is an horticultural perennial monocot that has edible, medicinal, ornamental values. However, gene family night not yet been analyzed systematically to date. Methods Therefore, we conducted a genome-wide study HcNAC identified total 113 members from genome. Results We found genes were unevenly distributed on 11 chromosomes. Phylogenetic analysis showed they could be categorized into 16 instinct subgroups. Proteins clustering together exhibited similar conserved motifs intron–exon structures. Collinearity indicated segmental tandem duplication might contribute great expansion lily, whose relationship was closer with rice than Arabidopsis . Additionally, tissue-specific pattern most had relatively higher expression abundances roots. RNA-Seq along RT-qPCR results jointly expressed differently under drought salinity stresses. Interestingly, HcNAC35 overexpressed watermelon, resilience transgenic lines much wild-type which revealed its wide participation abiotic response. Conclusion In conclusion, our findings provide new prospect for investigating biological roles lily.

Genome wide identification of BjSWEET gene family and drought response analysis of BjSWEET12 and BjSWEET17 genes in Brassica juncea

Abstract Background Sugars Will Eventually be Exported Transporter (SWEET) gene family is a unique type of sugar transporter that plays vital role in metabolic regulation, growth, development, and stress response multiple species. This study aimed to systematically identify the SWEET members detect regulation expression their potential roles Brassica juncea . Results A total 66 BjSWEET ( Sugar Transporter) genes distributed across 17 chromosomes were identified. The structure motifs relatively conserved, with all containing MtN3/saliva domain. Phylogenetic analysis revealed can classified into four subfamilies (Clades I, II, III, IV). Collinearity there 118 pairs segment duplicates, indicating some obtained via segmental duplication. promoter regions contained many plant hormone-related elements, stress-related growth development light-responsive regulatory elements. Furthermore, profiles levels differed among eight different tissues. qRT‒PCR six selected BjSWEET17.2 , BjSWEET17.4 BjSWEET12.2 BjSWEET12.3 significantly upregulated under drought treatment, suggesting these may respond B. Conclusion identified analyzed for first time, laying foundation further research on molecular mechanisms resistance providing theoretical guidance application other
